2. MEASURING RECTANGLES 4 th Grade Math MA.4.5 200 - Measurement

3. AREA AND PERIMETER OF RECTANGLES LESSON In this lesson you will be learning about how to find the area and perimeter of a rectangle! Please be sure to quietly work on this assignment individually. There will be a quiz at the end, so pay attention and make sure you understand everything! Don’t be afraid to go back to previous slides if you aren’t sure of a concept. Have fun!

4. INTRODUCTION QUIZ AREA PERIMETER SCAVENGER HUNT CLICK PLAY ON THE SOUND BUTTON BELOW IF YOU AREN’T SURE WHAT TO DO

6. Here’s a cool video from NASA!

7. Perimete r Perimeter = 2L + 2W Perimeter is the distance around a two-dimensional shape

8. Perimeter = 2L + 2W 2(4) + 2(10) = 8 + 20 = 28 feet

9. Area Area = L x W Area is the size of a surface

10. Area = L x H 10 x 4 = 40 feet

11. Are you ready for the Scavenger Hunt? In the next few slides, click on the image that has the correct height or width that you are looking for.

12. 3 ½ inches 4 inches 4 ½ inches 2 inches 5 ½ inches 3 inches 2 inches

15. 3 ½ inches 4 inches 4 ½ inches 2 inches 5 ½ inches 3 inches 2 inches

18. ? inches

21. 4 inches 2 inches To find the perimeter of the coffee mug, you would take the length times 2, plus the width times 2. Click the coffee mug when you think you have found the answer. If you need to, use the pen tool to show your work! 2(4) + 2(2) = 8 + 4 = 12
